SPECIFICATION forming part of Letters Patent No. 594,929, dated December 7, 1897. Application mea February 15,1897. sensing. 623,345. (No model.)

T all whom it may concern:

Be it known that I, GEORGE L. BEITNER, a citizen of the United States,residing at Bridgeport, in the county of Fairiield and State of Connecticut, have invented certain new and useful Improvements in Bakers-O ven Lamps; and I'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

This invention relates to bakers ovens,and has for its object to provide improved means for illuminating the interior thereof by means of a burner located on the outside.

Heretofore, so far as I am aware, in the construction of oven-lights there has been no provision for preventing the accumulation of fiour and other dust on the reflector, nor for protecting the micafrom becoming smoked or fractured. In my apparatus I provide means whereby the mica is normally protected by a shield inside the oven, and the reflector is normally in a position where it is impossible for dust to accumulate on its concave face, and said shield and reflector being adapted to be moved simultaneously to positions whereby the light is reflected into the oven, the amount of light being increased at the same time. v

My invention consists in the construction and combination of parts, substantially as hereinafter described and claimed.

In the accompanying drawings, Figure l represents a side elevation of my improved device, the casing or frame being in section and the parts being in their normal positions-that is, their positions when light in the oven is not needed. Fig. 2 represents a view similar to Fig. l, but with the movable parts in the positions which theyoccupy when light is thrown into the oven. Fig. 3 represents a section on line i/.y of Fig. l. Fig. 4

' represents a section on line .e ,e of Fig. 1.

Similar reference-characters indicate the same parts in all the views.

The frame or casing is indicated at l and is preferably a box-like casting having one side entirely open. This casting ts in the brickwork of an oven, the latter not beingrepresented, the open side being accessible to the attendant. The other or rear side of the frame is preferably formed with a bowwall, which has an opening provided with a sheet of mica, as at 2. A curved metallic shield 3 is provided with ears 4, which eX- tend through thecasing and are pivoted to lugs on the inside of the casing. This shield is adapted to closely cover and protect the mica when down and is provided with a lateral lug, as at 6, the purpose of which will presently be explained.

The reector is shown as consisting of a curved plate 7, having a circular burnished portion on its concave side, as indicated by dotted lines in Fig. 3. This plate or reiiector is provided with ears 8, pivotally mounted on a rod 9, which is supported by brackets l0, connected to the side .walls of the casing, and is also provided with a laterally-extending arm or lug 1l for a purpose presently described.

To one side wall of the vcasing is pivoted the three-armed lever, one arm of which forms a handle l2, and the upper arm 13 being forked to receive the sliding bar 14, which latter is slightly notched to receive the edge of the arm of the lever, whereby the latter may cause the bar to be reciprocated. Each end of the barlis rounded to form a cam-surface, and the front end extends through an opening 14 in the rear wall of the casing and is adapted to abut againstthe lug 6 of the shield and to swingthe latter upward when the bar is pushed against the said lug, as indicated in Fig. 2. The bar rides under one of the brackets lO'and is therefore prevented from being tilted off the arm 13 of the lever by the Weight ofthe shield. This movement permits the reiector to swing downward; but on the return movement of the lever and'sliding bar the cam-surface of the latter,whichis toward the reflector, abuts against the lug ll of said reiiector and rides under it, swingingthe reiiector up to a horizontal position under the top wall or roof of the casing. At the same time the shield is permitted to descend to protect the mica; but the weight of the reliector cannot tilt the bar, owing to the outer end of the said bar engaging under the lug or boss 15 of the casing. When the reflector is in this position, as shown in Fig. l, it is practically impossible for any dust to adhere to its vsurface, and when it is in the position shown in IOO Fig. 2 it is usually left so for such a short time that little or no dust will adhere thereto. However, such as might become lodged can be quickly removed by a cloth or brush when the reilector is back in its normal horizontal position.

As will be readily understood from Figs. 1 and 2, the bar 14 firmly supports either the reflector or shield in a horizontal position and may be left so by the attendant without possibility of swinging downward. A

A gas-burner 16 is located about midway between the center of the mica and the center of the reilector'when the latter is down casing, andan arm 20, which is connected by a link 21 with the lower arm 22 of the lever. These parts are so proportioned and connected that when the shield and reflector are in the positions shown in Fig. 2 the flame will be turned to its full height, but when in the positions shown in Fig. 1 the gas will be nearly, but not quite, shut off. When the oven is not in use, the supply of gas may be cut olf from the pipe 17 by any suitable valve. (Not shown.)

It will now be understood that when the attendant wishes to inspect the contents of an oven provided with my improved lighting apparatus he has only to lift the handle from the position shown in Fig. 1 to that shown in Fig. 2, and this will turn up the light and simultaneously raise the shield 3 and lower` v'the reflector, so that the light will be thrown through the mica.

I-Ie can leave the parts in these positions and go and inspect the oven through the ordinary sight-holes. Then by depressing the lever the flame is reduced, the reflector is raised to a position where dust cannot accumulate on it, and the shield is lowered to protect the mica from smoke in the oven and against injury.

Itis to be understood that I do not limit myself to the precise features of construction herein shown and described, but reserve the right to make all such changes or modiiications as would fall within the scope of my invention-for instance, to employ an electric lamp instead of a gas-burner.

Having now described my invention, what I claim is- 1. An oven-lighting apparatus, comprising in its construction a burner or lamp, a reflector pivoted on a horizontal axis, and means for moving the reflector to a substantially horizontal and raised position and for simultaneously reducing the illumination.

2. An oven-lighting apparatus comprising in its construction a burner or lamp, a `shield and reflector pivotally supported on opposite sides of said burner or lamp, and means for simultaneously raising one and lowering the other.

3. An oven-lighting apparatus comprising in its construction a burner or lamp, a shield and reflector pivotally supported on opposite sides of said burner or lamp, and means for simultaneously raising one and lowering the other and also controlling the amount of illumination.

4. The combination with the frame having the mica wall 2, of the shield 3 pivoted to the frame and having the lug 6, and the sliding bar 14 adapted to abut against said lug to swing the shield and to extend under sa'id lug to hold Vthe shield in raised position.

5. The combination with the frame, of a lamp or burner, the reflector 7 pivoted to the frame and having the lug or arm 11, and the sliding bar 14 adapted to abut against said lug or arm to swing the reilector and to extend under said arm to hold the reflector in raised position.

6. The combination with the frame or casing 1 having the mica wall 2, of the shield 3 and reflector 7 pivoted on opposite sides of said wall and each having a lug, the sliding bar 14 adapted to alternately abut against the lugs of the shield and reflector to swing them, means for reciprocating said sliding bar, and a lamp or burner between the said mica wall and reflector.

7. The combination with the frame or casing 1 having the mica wall 2, of the shield 3 and reflector 7 pivoted on opposite sides of said wall and each having a lug, the sliding bar 14 adapted to alternately abut against the lugs of the shield and reflector to swing them, the burner 16 and the lever having one arm connected to the sliding bar to reciprocate it and another arm having connections for controlling the illuminating power of said burner.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE L. BEITNER.
